cnABLEs 13. DE LAND, OF sroKAnn, WASHINGTON.

To all whom it may concern Be it known that I, CHARLES F. DE LANO, a citizen of the United States, residing at Spokane, in Spokane county and State of Washington, have invented certain new and useful Improvements in Manifold-Shields, of which the following is a specification.

The present invention relates to an im- 1 proved manifold shield for use in conneccooler or more condensed than the charge passing to the rear cylinders. By observation and test I have discovered that the cooling of the manifold and consequent condensing of the charge passing therethrough with its failure to ignite is due mainly to the current of air from the fan of the motor utilized to cool the engine casing and to cold air currents passing through the radiator at the front of the hood as the car travels. To overcome this objection and economic waste I have invented a shield to fit neatly and snugly over the intake and exhaust manifolds at the front of the motor whereby the manifolds are not only prevented from reaching a temperature too low for efficient fuel feeding, but. because of the presence of the shield the manifolds are positively heated, as by radiation from the engine casing, and the inclosed area within the shield retains the heat from radiation from the motor thus maintaining the proper temperature to the manifolds to insure reuired warmth for the charge passing t rough the manifold. V

By the utilization of my invention I am enabled to maintain the manifolds in suitable condition for warming and retaining the fuel charge at the proper degree of temperature as it is fed to the cylinders at the front of the motor, and in addition means are provided for ermitting ingress of cool air currents to t e manifolds within the shield, during warm weather to prevent:

combinations and arrangements of parts in Fig. 2 is a perspective view, detached, of

the shield.

In the preferred form of the invention as depicted in the drawings the shield is of metal, but it will readily be understood that other material may be used, suitable for the purpose, and the form and dimensions of the shield may vary to adapt it for different types of cars or motors. As shown especially in Fig. 2, the shield has a single side plate 1 and a forwardly declining top plate 2 of a width suitable for inclosing the intake manifold A and exhaust manifold B at the front of the motor C, and to enable close and intimate relationship of the parts the side of the shield that would be complementary to the front side 1 is omitted thus forming the inner wall of the shield by the outer side wall of the motor casing O.

The bottom plate 3 of the shield terminates near the rear open end of the shield and is extended downwardly in the form of an in tegral flanged which abuts against the front ofthe manifold A in Fig. 1, while the extreme rear edge of the side wall 1 overlaps the main portion of the manifold and entirely covers the front branch thereof as well as the front end of the exhaust manifold B. 7

The front wall 5 of the shield, which is located at the front of the motor and at the rear of the fan F, is fashioned with a series of horizontally disposed slots 6, which may be closed or partially closed by the draft regulator 7 in the form of a metal plate and fashioned with transverse slots 8 complementary to and adapted to register with the slots 6 of the front plate of the shield. The draft regulator is retained and guided in a series of integral lugs or flanges 9 suitably spaced at the opposite edges of the front plate of the shield, and by means of the transverse flange 10 at the top end of the draft plate, said plate may be moved vertically in the guide lugs 9 to desired position for controlling the size of the openings of the slots in the front plate and draft plate to regulate the passage of air currents to the interior of the shield. A set screw 11 is provided in one of the lugs 9 by means of which the plate'may be secured in adjusted position, and in this manner the circulation of air through the regulated openings at the front of the shield through the interior of the shield and out through the open back end thereof, may be controlled. In cold weather the slots at the front of the shield may be entirely or partially closed to secure the required temperature within the shield, and in warm weather the slots may be left entirely open to permit circulation of air through the shield from front to rear.

In attaching the shield to the motor casing 1 provide a pair of spaced apertures 12 in the side wall of the shield which fit over the complementary stud bolts 13 secured in the engine caslng for the purpose of fastenll'lgllllfi manifolds totheengine, and two ter bars have flat heads 16 to engage and bear against the side wall 1 of the shield and in addition hold the manifolds in place.

By this means the shield may be attached or detached with facility, and is rigidly and firmly held in place against rattling or dis lodgment, as it will be apparent that the contact of the shield with the several parts of the casing and manifolds providesja firm support for the shield. The heat retaining chamber thus provided receives heat radiated from theengine casing and protects the manifolds from inflowing cold air currents from the fan or through the radiator for the purpose described.

Having thus fully described my invention, what I claim is A shield forthepurpose described comprising a single side wall, a closedtop and partially closed bottom with a rear opening, a slotted front wall, an adjustable, slotted front plate, and a downwardly projecting rear flange on the bottom wall thereof. 1

In testimony whereof I afiix my signature.
